Convert CSV to JSON
What is CSV?
CSV
CSV (Comma-Separated Values) stores tabular data as plain text with delimiters (typically commas, semicolons, or tabs). Each line represents a row; delimiters separate columns. No formatting, formulas, or multiple sheets—just raw data. Universal compatibility across platforms. Extremely simple structure. Human-readable. Maximum size limited by available memory. Ideal for data exchange and import/export operations.

Uses curly braces for objects, square brackets for arrays. Supports strings, numbers, booleans, null. Maximum size limited by parser implementation. Universal data interchange format for APIs and configuration. Based on JavaScript syntax but language-agnostic.
